The content of this article is an excerpt from the ASPA training course The Secrets of Printing T-Shirts and How to Make Big Money!Custom printed transfers can be another way to add a profit center to your t-shirt printing business. Screen printing transfers (especially single color transfers) is easy and they can be produced very quickly if you have the right equipment. Many shops started printing transfers as a side line and developed into transfer specialists producing only custom transfers exclusively because of the high profit factor. Another great feature of custom transfers is for servicing repeat customers who have small orders. By printing extra transfers of the customer's art, you can save the transfers for their next order. And without having to burn new screens, you can fill the next order easily and quickly.
